A Rust library for multi-protocol passive network fingerprinting, combining p0f-style TCP/HTTP analysis with JA4-style TLS client analysis.
Huginn Net is a multi-protocol passive fingerprinting library written in Rust that enables network analysis by inspecting TCP/IP packets and TLS handshakes without sending probes. It provides insights into operating systems, applications, browsers, and network infrastructure by combining p0f-style TCP fingerprinting with JA4-style TLS client analysis. This tool is valuable for security analysis, asset discovery, and application monitoring.
Security analysts, network engineers, and developers building network monitoring, threat detection, or compliance tools that require passive identification of devices and applications. It is also suitable for researchers and forensic investigators analyzing traffic patterns and TLS usage.
Developers choose Huginn Net for its validated accuracy matching the original p0f tool, its pure Rust implementation offering memory safety and zero-cost abstractions, and its multi-protocol support combining TCP, HTTP, and TLS analysis in a single library without requiring third-party tools like tshark or Wireshark.
Multi-protocol passive fingerprinting library: TCP/HTTP (p0f-style) + TLS (JA4-style) analysis in Rust
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Combines p0f-style TCP, HTTP, and JA4-style TLS fingerprinting in a single library, enabling comprehensive network analysis without multiple tools, as highlighted in the key features and network stack table.
Matches original p0f detection accuracy across device categories like Windows, Linux, and mobile devices, with validation against real-world traffic ensuring reliable results.
Pure Rust implementation offers memory safety and zero-cost abstractions, with benchmarks showing high packet processing speeds (e.g., TCP at 83.3M pps) for real-time monitoring.
Provides separate crates for TCP, HTTP, and TLS analysis, allowing focused use cases and reduced overhead, as detailed in the crates section and performance optimization notes.
Does not implement JA4+ components due to licensing restrictions, limiting advanced TLS fingerprinting capabilities compared to full JA4+ suites, as admitted in the TLS JA4 Fingerprinting section.
Live packet capture requires libpcap, which may not be pre-installed on all systems (e.g., Windows), adding setup complexity despite being common on Linux/macOS, as noted in the Quick Start.
As a Rust-specific library, it lacks the extensive plugin ecosystem, community tools, and graphical interfaces available for established alternatives like Wireshark or p0f, potentially limiting broader adoption.
